Are the sensors created? Do your see them under Developer Tools - States?
Have you looked through all the SNMP walk and see if you could find the ink levels ? They might be somewhere else. It also looks like you only have 2 cartridges - black and tri-color so you’ll only need 2 sensors

both return 0 @Holdestmade
Can you post the whole SNMP WALK output ?
What level are your inks at ?
I don’t think that officejet is supported, I have hp envy, also 2 inks, can’t see ink level either with snmp… See my reply with screenshots about 15 posts above

Went off down the link of installing ink , only to discover this only works for a limited range of inkjet printers. I have a Brother laser printer so next step was to try SNMP, which is supported by my printer. This turned out to be a nightmare, so ended up scraping the info via curl from a webpage.
Used your card setup - thanks!
can you show us how you did it with curl?

My Brother DCP-9055CDN laser printer has a config webpage by navigating to it’s IP address. Part of the page displays toner levels. The problem with Brother printers is that it does not show an absolute value for toner levels (in fact via SNMP I think it displays -3 meaning OK, -2 meaning low and -1 mean empty - or some such rubbish so that’s why I didn’t use SNMP). On the webpage it displays coloured boxes to indicate toner capacity - each black box is 10%. So for the curl I went to the webpage and counted up the number of black boxes for each colour. I actually run 4 curls - couldn’t work out how to do it all in one!
Here is part of the webpage I need to scrape:
So the curl command is made up of 4 bits - display the webpage, find the appropriate colour toner section plus the following 2 lines, find the black/white boxes line, count how many black boxes. The value_template is needed to add a zero onto the end of the count (ie 4 black boxes indicates 40%, not 4%).
Here is the config in configuration.yaml under sensor:
# Get toner levels in printer
- platform: command_line
name: Brother Cyan Toner Level
command: "curl http://192.168.1.99/etc/mnt_info.html?kind=item | grep -A 2 'Toner Cyan' | grep -o x25a0 | wc -l"
scan_interval: 86400
value_template: >-
{{ value ~ "0" }}
- platform: command_line
name: Brother Magenta Toner Level
command: "curl http://192.168.1.99/etc/mnt_info.html?kind=item | grep -A 2 'Toner Magenta' | grep -o x25a0 | wc -l"
scan_interval: 86400
value_template: >-
{{ value ~ "0" }}
- platform: command_line
name: Brother Yellow Toner Level
command: "curl http://192.168.1.99/etc/mnt_info.html?kind=item | grep -A 2 'Toner Yellow' | grep -o x25a0 | wc -l"
scan_interval: 86400
value_template: >-
{{ value ~ "0" }}
- platform: command_line
name: Brother Black Toner Level
command: "curl http://192.168.1.99/etc/mnt_info.html?kind=item | grep -A 2 'Toner Black' | grep -o x25a0 | wc -l"
scan_interval: 86400
value_template: >-
{{ value ~ "0" }}```

Using a cheap-dumb Brother BW Laser HL-1210W. Web page of the printer has Maintenance Information page which shows the % of Black Toner remaining. Solved it like this:
- platform: command_line
name: Brother Toner Level
command: 'curl http://192.168.1.10/general/information.html?kind=item'
scan_interval: 86400
value_template: >-
{% set status = value | regex_findall_index('[0-9][0-9].[0-9][0-9]%', index=1) %}
{{ status }}
Pff, mine does not, all fancy widgets and graphs only

Trying to get this working on my mx922. Looks good in the add-on log:
nk 0.5.3 (c) 2018 Markus Heinz
Canon MX920 series
Black: 60%
Photoblack: 80%
Yellow: 80%
Magenta: 70%
Cyan: 70%
-------------------------------------------
Parameters:
MQTT Host = 192.168.1.9
Printer IP address = 192.168.1.50
Sleep interval = 3600
Brand = Canon
Type = MX920
But when I try to add the sensors, the config checker gives me:
Platform error sensor.ink - No module named 'custom_components.ink.sensor'
What files/folders should I have under custom_components ?

@bmorgan @febalci Any idea if it’s possible with my model?
Can you help with the code?
My envy looks the same, would be difficult I think

The supported printers for the ‘ink’ command is: http://libinklevel.sourceforge.net/#supported And i see a HP Deskjet 3820 there… Feels like it could also have support for 3830. Have you tried it?
What does the ink command actually do?
